An ophthalmologic apparatus includes: a head unit having an optical system capable of receiving light reflected from a subject's eye; a drive mechanism that movably holds the head unit; an alignment detection unit that detects a position of the subject's eye relative to the head unit; and a control unit that controls the drive mechanism. The drive mechanism includes at least two arms rotatably connected together, at least two first rotation support mechanisms and at least three second rotation support mechanisms which allow the head unit to move, and at least five driving units for driving the rotation support mechanisms. The control unit is capable of controlling the driving units using a measurement result of the alignment measuring unit to align the head unit and the subject's eye with each other.

A retinal imaging system includes an image sensor for acquiring a retinal image and an illuminator for illuminating a retina to acquire the retinal image. The illuminator surrounds an aperture through which an image path for the retinal image passes before reaching the image sensor. Illumination sources surround the aperture.

An ophthalmic apparatus for examining an examinee's eye, comprising a face support member to support an examinee's face, a human detection member to detect whether or not the face is supported by the face support member, a notification member to give an announcement to an examinee or an examiner, and a control member to control the notification member based on a detection result of the human detection member.

Portable corneal topographers and portable corneal topographer modules are disclosed. In one embodiment, a corneal topographer module comprises a housing having a first aperture and a second aperture formed therethrough; and a plurality of optical components disposed within the housing. The plurality of optical components are arranged to direct light generated by a light source through the first aperture to the cornea via a first optical channel when a cornea of a patient's eye is located adjacent to the first aperture; and direct reflected light from the cornea into the housing through the first aperture and to a light detector of a mobile device via a second optical channel when the corneal topographer module is mechanically coupled to the mobile device.

The present application describes the addition of various feedback mechanisms including visual and audio feedback mechanisms to an ophthalmic diagnostic device to assist a subject to elf align to the device. The device may use the visual and non-visual feedback mechanisms independently or in combination with one another. The device may provide a means for a subject to provide feedback to the device to confirm that an alignment condition has been met. Alternatively, the device may have a means for sensing when Acceptable alignment has been achieved. The device may capture diagnostic information during the alignment process or may capture after the alignment condition has been met.

A line-of-sight detector including: a memory in which a plurality of eyeball features are registered in a mode of associating each of the plurality of eyeball features with a corneal radius; and a processor configured to perform a process for detecting a line of sight of a person, wherein the process includes: calculating a feature amount of an eyeball of a person who is gazing at a first gaze point of gaze points in an image; determining an eyeball feature of the person in accordance with a feature amount of the eyeball that corresponds to the first gaze point in the plurality of eyeball features registered in the memory, and the calculated feature amount of the eyeball; and calculating a calibration parameter for a line of sight of the person in accordance with the feature amounts of the eyeball that are included in the determined eyeball feature.

A method may include controlling alignment of the eye in an ophthalmological imaging device that includes an imaging system with a given optical axis. The method may include the formation, on a two-dimensional detection plane, of an image of an element located in a plane of the pupil of the eye. The method further includes the determination of a lateral position of the pupil of the eye with respect to a point of origin of a reference frame of the imaging system, on the basis of the position of the image. The method further includes the analysis of a state of focus of the image. The method further includes the determination of an axial position of the pupil of the eye with respect to the point of origin of the reference frame of the imaging system, on the basis of the analysis of the state of focus.

A fundus photographing apparatus includes: a photographing unit including a front photographing optical system that forms, on a pupil of an examinee's eye, an illuminating light projection region and an illuminating light receiving region next to each other in a first direction, the front photographing optical system scanning a fundus of examinee's eye with illuminating light to acquire two-dimensional reflection image of the fundus; a driver that moves the photographing unit relative to examinee's eye; and a processor that switches, between a first and a second alignment mode, a control of guiding a positional relation between the examinee's eye and the photographing unit, the positional relation being guided to a first alignment state in predetermined positional relationship in the first alignment mode, and being guided to a second alignment state displaced at least in a direction crossing the first direction from the first alignment state in the second alignment mode.

An apparatus for producing a non-mydriatic fundus image is disclosed. The apparatus can include a processor and memory, as well as an illumination component and a camera with a variable focus lens. The apparatus can be configured to adjust the focus of the lens to a plurality of different diopter ranges and capture at least one image at each of the plurality of different diopter ranges. Using the captured images, three-dimensional maps of the fundus may be generated. Three-dimensional maps of the fundus may be used to screen or diagnose various diseases.
